Abstract: The toroidal type continuously variable transmission includes: first and second disks concentrically disposed on each other and supported such that they can be rotated freely; a pair of trunnions; a pair of displacement shafts respectively including support shaft portions and pivot shaft portions; a plurality of power rollers interposed between and held by the first and second disks; a plurality of thrust ball bearings respectively for supporting their associated power rollers; and, a plurality of thrust needle bearings respectively interposed between the outer surfaces of outer rings respectively forming the thrust ball bearings and the inner surfaces of the trunnions. A retainer for retaining the thrust needle roller in a freely rollable manner is formed of a single plate, and is carbonitrided, while the surface hardness Hv of the retainer is set higher than or equal to 550.
